| Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es> | |
| This card is basically the same as all the rest (Bt484A, Philips tuner), | |
| the main difference is that they have attached a programmable attenuator to 3 | |
| GPIO lines in order to give some volume control. They have also stuck an | |
| infra-red remote control decoded on the board, I will add support for this | |
| when I get time (it simple generates an interrupt for each key press, with | |
| the key code is placed in the GPIO port). | |
| I don't yet have any application to test the radio support. The tuner | |
| frequency setting should work but it is possible that the audio multiplexer | |
| is wrong. If it doesn't work, send me email. | |
| - No Thanks to Leadtek they refused to answer any questions about their | |
| hardware. The driver was written by visual inspection of the card. If you | |
| use this driver, send an email insult to them, and tell them you won't | |
| continue buying their hardware unless they support Linux. | |
| - Little thanks to Princeton Technology Corp (http://www.princeton.com.tw) | |
| who make the audio attenuator. Their publicly available data-sheet available | |
| on their web site doesn't include the chip programming information! Hidden | |
| on their server are the full data-sheets, but don't ask how I found it. | |
| To use the driver I use the following options, the tuner and pll settings might | |
| be different in your country | |
| insmod videodev | |
| insmod i2c scan=1 i2c_debug=0 verbose=0 | |
| insmod tuner type=1 debug=0 | |
| insmod bttv pll=1 radio=1 card=17 | |
